Anyone got any suggestions for a good amp in a pedal that covers decent clean and dirty sounds. I use a Kemper for live running out to the house PA and a powered monitor on stage. My worry is that the Kemper dies on me mid-gig so I'm looking for some back-up. I need a pedal that will give me a decent amp-sim tone and that can run straight into a powered speaker and do a good impression of an amp + monitor. Something that does a good clean but has an overdriven sound as well. Anything out there?
